200825499 九、發明說明： 【發明所屬之技術領域】 本發明係有關於一種光學元件，屮使3 1千尤其疋—種透明光學元件之制 造，係例如一眼科鏡片。 衣 【先前技術】 自光學元件中製造-眼科鏡知的1上述光學元件之表 面上平灯排列有-組單元(cells)。其中各單元被密封且包含有具 性質之物質。於各單元中適#地選擇其中之所包含之” 得製造眼科鏡片所需要之光學特性。並且，鮮的_在單元中^ 換具有不同光學特性之㈣，可得㈣林同光學舰之鏡片。因 而，大量且具有不同光學功能之鏡片可_同—光學元件的更換模 式而取知’因而提供了一種經濟有效的製造方法。 此外，將單元密封係用以防止單元内物質與相鄰單元内物質相 混合。並透過最初於較單元中放置不同之物質而獲得之鏡片之光 學特性永久地保留，並衫鏡#之使用壽命所限制。 將早兀挽封之另-優點係為—般所使用之單元内物質很可能處 於液態或凝㈣。且實際上，餅特定光學特性而言，使用液態或 凝膠態之物質較使關態物f為優。舉例而言…般液態或凝膠態 之具有光致變色性（_。血。mic)物質，較固態之光致變色性物質， 對於發光度之變化，具有較高的反應速度。 最後目艮科鏡片通常透過切割一光學元件獲得，此光學元件 200825499 沿著-相應於適合佩戴者之框架之輪廓線切割。容納有此光學元件 之光學特性物質的單元被密封係用以防止此物質之主要部份自光學 元件中抓出。貝際上，僅位於光學元件切割輪廊線處之單元中所内 ‘含之光學特性物質流失。而透過於此光學元件中被切割輪廓線區域 -上使用小尺寸之單元，而使得鏡片之光學特性得以保持。因此，使 用透過切割-原始光學元件製造眼科鏡片之方法中，單元之使用與 以液態或凝膠態形式存在之光學特性物質之使用相結合。 然而，對於眼科鏡片而言，單元之使用具有美觀上及光學上的 缺陷。實際上，大尺寸單元，即單元之尺寸的邊長大於〇5腿（毫 米）之單兀，對於使用者而言，能引起視覺障礙。此外，由於大尺 寸單祕為肉眼可見的，並不則I人使用它。為了避免單元之 尺寸過大而肉眼可見，而使用尺寸足夠小之單元，則又會帶來彩虹 色及乳狀薄霧等問題。且於習知技術中，這些小尺寸單元所造成之 缺點係由整組單元所帶來的繞射即散射作用所引起，更尤其由各單 元間用以隔離之隔壁所引起。 【發明内容】 ^因此，本發明之目的在於減少光學元件中單元之使用而造成光 學上及美觀上的缺點。 為達此目的，本發明提出了一種光學元件，其包含有至少一組 〜月早TG(cells)，係排列平行於該光學元件之一表面，而各單元被密 封且内含有一具有光學特性之物質，沿著平行於光學元件之表面測 200825499 里’此組單元中之單元具有複數種尺寸。 根據本發日种，欲烟具林同尺寸之單元，其料學元件 表面上的分佈，最好是依照其不同尺寸之單元的功能加以分佈 —於光干7L件中_可能產生實質障礙之區域，透過明智地確定單 二使得單元之肉眼可見度與所產生之繞射及散射作用能 被避免t減少。因此，透過如此較單元之尺寸，可使光學單元及 /、可&仔之翻度具有最佳化。*在本發明巾，當穿過上述光 件之影像沒有明顯對比失真之時，也就是說，當穿過所述光學=件 所形成之影像沒有損害影像品質之時，認為此光學元件是透明的。 此外’不同尺寸之單元能於光學元件製造之單一步驟中形成， 且此光學元件之製造時間並沒有由於製造不同尺寸之單元而增加。 誶細而言，沿著平行於光學元件之表面測量，至少立中一單元 ^尺寸的邊長為α5絲至5絲之間。且至少在具奴寸高於此尺 寸的w之一平面中’所述之單元不帶來任何穿過此光學元件之光 線的實質繞射或散射。在此平面中，所述單元相應具有—連續且高 視覺透明之外觀，而沒有彩虹色或薄霧等現象。此光學元件，以及 相應地自此光學兀件所獲得之光學單元亦符合美觀。這一點對眼 科應用而言尤其有利，對眼科應用而言美觀更為重要。 、而沿著平行於光學元件表面測量，光學元件之部分單元之尺寸 ，、〜C】、於2GQ被米’並且其較佳為⑽微米以下。而上述單元 對肉眼而言是不可見的’因此並沒有實質上降低此光學元件或自此 200825499 光學元件獲得之美觀。 祀據本U之較佳實施例，此組單元在光學元件之中央區域 具有至少一較大尺寸單元，以及介於此中央區域及光學元件表面^ 之二具有較小尺寸單元。因此，較大尺寸單元在此光學元件 、一、具有極佳的美感及光學傳輸特性。同時，透過改變相鄰 k單H辟痛物質’較小尺寸單元肋調整及改變光學元 外圍區域之光學特性。進—步而言，光料件可沿著位於外圍區域 之輪廓線_ ’而無技射央區域巾之較大尺寸單元巾之所内含 之光學特性物質。舉例而言，中央區域中之較大尺寸單元之尺寸的 邊長可大於0.5毫米，並且相區財之較小尺寸單元之尺 可小於200微米。 、长 、真1意地，單元之尺寸可在光學元件表面之巾央區域及此表面之 地緣連續梯度之方式變化。因而可獲得光學元件巾央區域及外 =區域中之單元尺寸之漸歧變，並且有助於此光學元件及自此光 子70件中獲*之光學單元之美觀。並且依據此光學元件之外圍區 或此連續單元尺寸梯度可任意變化。 在本發明另一實施例中，單元之尺寸也可在光學元件表面之中 央區=及此表面之邊緣間以不連續梯度之方式抑，單元尺寸間之 、芦! 生有助於優化此光學元件及自此光學元件中獲得之光學單元 之光學特性。 顯然，在本發_文巾，财單元尺寸之減組合是可能的 200825499 因此在-給定之光學元件中，很可能具有至少一區域，龙 光學元件表蚊巾央區取此絲之魏㈣連續梯度之 方式受化，亚且具有至少另一第二區域，其中單元之尺寸可在光風 兀件表面之中央區域及此表面之邊緣_不連續梯度之方式錄化。子 …由於各單元被密封，使得部分單材内含之光學特性物質可以 液態或凝職之形式存在。而以此形式存在之㈣可財較佳的光 學特性，例如光致變色性之反應速度。此外，也較容易獲雜定的 光學特性，例如某一光學參數之特定值。而實際上，可透過混合注 入具有不同參數值之液態及凝膠_式之物f，而_所期望參數 其中，各單元中内含之光學特性物質，其光學特形可為著色性、 光致變色性、偏光性以及折射率等特性。詳細而言，此組單元中有 些單兀可包含有物f之光折射率相異於其他單元巾物質之光折射 率。於此種情況下’时有不同折鱗之师的單元可以具有不同 之單元尺寸。而詳細而言，此單元之尺寸可根據待校正之肉眼屈折 異常之評估來調節。 本發明之一種光學元件可用於製造一光學單元，其中此光學單 兀係可為眼科鏡片、驗光學儀器之透鏡、濾、鏡、光學畔透鏡、 眼睛保護鏡以及光學照明設備。 本發明更提出-種透過切割上述光學元件而製成之眼鏡片。進 -步而言，至少在此光學元件上鑽穿—孔洞，_將此眼鏡片固定 200825499 至-框架上。建議在眼鏡片中部份小尺寸單元形成鑽孔。 在上述眼鏡片中，根據待校正肉眼之屈折異常，部分單元 包含具蝴·術以趟^財幫鏡之表面進行 不冋_整。雜而言，如此製造之透鏡可以為—漸進式透鏡。 此外透鏡之早兀中内含之物質可以為光致變色性物質，其中 此物質較佳為液態或凝膠態之形式存在。 /、 【實施方式】 二如「第1圖」所示之光學耕係、為用以製造眼鏡片之毛链10。

片上能夠鑽出孔洞14，舉例而言，其可驗容納安裝固定至框架的 螺絲。 毛坯10的一般形狀可遵照工業標準來設計，舉例而言，可如「第 1圖」及「第3圖」所示，其具有直徑為60毫米(mm)之圓形邊緣B、 一刖侧凸面12以及一後侧凹面13。而傳統的切割、修剪及鑽孔工具 均可用以加工毛坯1〇而獲得眼鏡片n。 在第1圖」及「第2圖」中，表層之一部份移除區域顯示了 毛趣10及眼鏡片11之晝素結構。此結構係由單元㈣职5 (或稱微 至mircotanks)之網狀結構所組成，其中單元15形成於毛坯]〇之一 披復層17中（如「第3圖」所示）。在這些附圖中，披覆披覆層i7、 單元15(或彳政室)之尺寸被加以放大，以便於觀察附圖。 根據本發明之第一實施例，毛坯10之表面被分為複數個區域， 於本實施例中，被分為四個區域，即外圍區域Z1、過渡區域Z2、 Z3及中央區域Z4四個區域。並沿平行於毛述之表面測量，可得 單元15之尺寸D，且於不同區域中，所得單元15之尺寸亦有所變 化。 在外圍區域Z1中，單元15可具有小於2〇微米之尺寸D。舉例 而。，這些尺寸大約為5至10微米之間。因而，當輪廓線c位於外 圍區域Ζ1中日^*，如此的單元尺寸使得於切割毛链時，可以不損 11 200825499 失大部分單it 15中所内含之 /、为九学特性之物質。毛坯10之来學 特性僅透過在輪廓線c中切到一 f 尤予 σ小於大約30微米之外圍帶而改變。 而如此窄的切割外圍帶係為 — 个了見的進一步而言，外圍區域 Ζ1中之早兀15是不可見的。 而t中^區域Ζ4’早疋15之尺㈣則較適合為大於5毫米， 因此’攻些早7〇產生肉眼不可見的繞射或散射作用，因此並不對佩 戴者產生視覺障礙也不對—幅眼鏡片造成美觀上的衡擊影響。舉例 而言，在中央區域Ζ4中，罝分κ ^ t 早兀15之尺寸D大約為8毫米至1〇 米之間。 在過渡區域Z2及Z3中，κ > η 1 ，/、早70 15之尺寸D較適合介於外g 區於Z1及中央區域Z4中的單亓 〇早70 155之尺寸D之間。舉例而言，j 兀15之尺寸D在過渡區域Z2中係 τ %為大約50被米，而在過渡區超 Z3中係為大約1〇〇微米。 ”中單兀15被壁18所分隔，且隔壁18將單元υ密封。 舉例而言’沿著平行於毛这1G之表面測量，隔壁18之厚^大約 為0.1微米至5微米間。且隔㈣垂直於毛㈣之表面，其高度可 為1财至1G0微米間，而較佳的情況係介於職至職米^。 單元15可以方格（如「第4圖」所示）或以六角格子（如「第 5圖」所示）之形式排列’並且，舉例而言，隔壁18之厚度d為2 齡。因此單元15之尺寸0等於方形或六角形之側邊邊U其中， 最佳實施樣祕行程此六肖贱蜂窩型之格子，因為它可以使此組 12 200825499 單兀具有最佳賴麵度。_，本發财單幻5之格子形狀並不 限定於方形或六㈣，而凡與晶職何學相容之财可能類型之格 子形狀都是可實施的。例如單元15之格子形狀缝成為矩形、三角 形或八角形，而，遵照上蚊義之單元15尺寸d將多種不同類 型之格子雜合糾職域輯元较可財麵。即毛㈣中 任一區域中之格子形狀與另中之格子形狀是可以不同。

有整組單元15之坡覆層17上，更覆蓋形成有-定數量之附加層 19、20。而這些附加層具有特定功能，例如耐衝擊性、抗划傷性、 13 200825499 著色性、抗反射性、防污垢性等性能。於本實施例中，披覆居 接形成於透明基板16之上，但是可理解的是，在披覆層/及透明 基板更可形成有一或更多的中間層。 此外，硬數組單元層積形成於基板16上之堆積層是可能的。因

能夠被用於此應用領域中的物質係為中孔性材料、液晶體及盤 形成分。所述之液晶體可透過-聚合反應進行固定，例如可透過= 射產生。因而液晶體可以選擇向通過液晶體的光波中引入一預先設 定之光學延遲之方式固定。而對於中孔性材料之情況而言，材料之 折射率可以透過變化其孔隙度而加以控制。此外，另—種可使用的 物質是光聚合物’光聚合物之一公知的性質就是其可以在藉由照射

[Prior Art] Manufactured from an optical element - an ophthalmic mirror 1 The above-mentioned optical element has a flat lamp arranged on a surface of a group of cells. Each of the units is sealed and contains a substance of a nature. The optical characteristics required for the manufacture of ophthalmic lenses are selected in each unit. Moreover, the fresh _ in the unit has different optical characteristics (4), and (4) the lens of the same optical ship Thus, a large number of lenses with different optical functions can be known from the replacement mode of the optical elements' thus providing a cost-effective manufacturing method. In addition, the unit sealing system is used to prevent intra-cell materials and adjacent units. The internal materials are mixed and the optical properties of the lens obtained by initially placing different substances in the unit are permanently retained, and the life of the mirror # is limited. The material used in the unit is likely to be in a liquid state or condensed (4). In fact, in the specific optical properties of the cake, the use of a liquid or gel state is superior to the off-state f. For example, liquid or condensate A colloidal photochromic (_. blood) material, a solid photochromic substance with a high reaction rate for changes in luminosity. Often obtained by cutting an optical component, the optical component 200825499 is cut along a contour corresponding to a frame suitable for the wearer. The unit containing the optical property of the optical component is sealed to prevent a major portion of the material. Grabbing from the optical element. On the shell, only the optical characteristic material contained in the unit at the optical element cutting wheel line is lost. Through the cut area of the optical element, the small size is used. The unit is such that the optical properties of the lens are maintained. Therefore, in the method of manufacturing an ophthalmic lens through a cut-original optical element, the use of the unit is combined with the use of an optical property substance in the form of a liquid or gel state. For ophthalmic lenses, the use of the unit has aesthetic and optical defects. In fact, the large-sized unit, that is, the side of the unit has a side length greater than that of the 〇5 leg (mm), for the user, Causes visual impairment. In addition, because the large size single secret is visible to the naked eye, it is not used by I. In order to avoid the unit The size is too large to be visible to the naked eye, and the use of a unit of sufficiently small size brings problems such as iridescence and milky mist. Moreover, in the prior art, the disadvantages caused by these small-sized units are The resulting diffraction or scattering effect is caused, in particular, by the partition walls between the cells for isolation. [Invention] Therefore, the object of the present invention is to reduce the use of the elements in the optical component to cause optical and aesthetic appearance. Disadvantages of the Invention In order to achieve the object, the present invention provides an optical component comprising at least one set of TGs, which are arranged parallel to one surface of the optical component, and each unit is sealed and contained There is a substance with optical properties, measured along the surface parallel to the optical element in 200825499. The unit in the unit has a plurality of sizes. According to the present invention, the unit of the same size is used on the surface of the material element. The distribution is preferably distributed according to the function of the units of different sizes - in the light-drying 7L parts - areas where physical obstacles may occur, by judiciously determining the single The obtained cell of the visible diffraction and scattering can be avoided arising reduced t. Therefore, by the size of the unit, the optical unit and /, can be optimized for turning. * In the invention, when the image passing through the optical member has no significant contrast distortion, that is, when the image formed by the optical member does not impair the image quality, the optical component is considered to be transparent. of. Furthermore, 'differently sized units can be formed in a single step of optical component fabrication, and the manufacturing time of this optical component is not increased by the manufacture of cells of different sizes. Specifically, along the surface parallel to the optical element, at least one unit of the unit has a side length of between 5 and 5 filaments. And at least in the plane of one of the ws having a size above this size, the unit does not introduce any substantial diffraction or scattering of light passing through the optical element. In this plane, the unit has a continuous and highly visually transparent appearance without iridescence or mist. The optical element, and correspondingly the optical unit obtained from the optical element, is also aesthetically pleasing. This is especially beneficial for ophthalmic applications, which are more important for ophthalmic applications. And measured along parallel to the surface of the optical element, the size of a part of the unit of the optical element, ~C], is 2> in m' and is preferably (10) or less. While the above unit is invisible to the naked eye, it does not substantially reduce the aesthetics of the optical component or the optical component since 200825499. According to a preferred embodiment of the present invention, the set of cells has at least one larger size unit in a central region of the optical element, and a smaller size unit between the central region and the optical element surface. Therefore, the larger size unit has excellent aesthetic and optical transmission characteristics in this optical component. At the same time, the optical characteristics of the peripheral region of the optical element are adjusted and changed by changing the adjacent k-H-paining substance's smaller size unit rib. In the further step, the optical member can be along the contour line _' of the peripheral region without the optical characteristic substance contained in the larger-sized unit towel of the technical region. For example, the size of the larger sized unit in the central region may be greater than 0.5 mm, and the smaller sized unit of the phase region may be less than 200 microns. Long, true, the size of the unit can vary in the manner of the central region of the surface of the optical element and the continuous gradient of the surface of the surface. Thus, the gradual change in the cell size in the area of the optical element and the outer area of the optical element can be obtained, and contributes to the aesthetics of the optical element and the optical unit obtained from the photon 70. And depending on the peripheral area of the optical element or the continuous unit size gradient, it can be arbitrarily changed. In another embodiment of the invention, the size of the unit can also be in the form of a discontinuous gradient between the central region of the surface of the optical element and the edge of the surface. Optical properties of the component and the optical unit obtained from the optical component. Obviously, in this hair _ scarf, the combination of the size of the financial unit is possible 200825499. Therefore, in a given optical component, it is likely to have at least one region, the dragon optical component table mosquito area is taken from the silk (four) continuous The gradient is subdivided and has at least another second region, wherein the size of the unit can be recorded in the central region of the surface of the windshield and the edge of the surface_discontinuous gradient. Since each unit is sealed, the optical characteristic substance contained in a part of the single material may exist in a liquid or coagulating form. In this form, (4) better optical properties such as photochromic reaction speed. In addition, it is also easier to obtain a given optical characteristic, such as a specific value of a certain optical parameter. In fact, it is possible to inject a liquid and a gel having different parameter values by mixing, and the desired parameter, wherein the optical characteristic substance contained in each unit, the optical characteristic can be coloring, light. Characteristics such as discoloration, polarization, and refractive index. In detail, some of the units in the group may contain the refractive index of the light of the material f which is different from that of the other unit materials. In this case, the units of the divisions with different scales may have different unit sizes. In detail, the size of the unit can be adjusted based on the assessment of the gross refractive error to be corrected. An optical component of the present invention can be used to fabricate an optical unit, wherein the optical monomolecular lens can be an ophthalmic lens, a lens for an optical inspection instrument, a filter, a mirror, an optical side lens, an eye protection mirror, and an optical illumination device. The present invention further proposes an ophthalmic lens produced by cutting the above optical element. In the case of the step, at least the hole is drilled through the hole, and the lens is fixed to the frame 200825499. It is recommended to form a drilled hole in some small-sized units in the ophthalmic lens. In the above spectacle lens, according to the abnormality of the inflection of the naked eye to be corrected, some of the units include the surface of the butterfly to perform the correction. Miscellaneously, the lens thus produced can be a progressive lens. Further, the substance contained in the early sputum of the lens may be a photochromic substance, and the substance is preferably present in a liquid or gel form. [Embodiment] The optical cultivation system shown in Fig. 1 is a hair chain 10 for manufacturing an ophthalmic lens. If the 'optical lens' contains a lens. The purpose of the film is to fit the eyeglass frame _, a turn of the eye and a correct vision. The lens can be selected from the lens of the point, the single f, the point lens, the Wei point Wei, the three _ Wei and the gradual change. The ophthalmic optics is a preferred field of the present invention, however, it can be understood that = hairpin 1__ is used in other types of tamper-evident units, for example, a lens: a lens, a filter, an optical alcohol lens, Eye-protecting, optical illumination wire 1 In the present invention, ophthalmic optics includes not only lenses, but also contact lenses and eye implants. The '2 diagram' indicates the _ ophthalmic lens u, which is cut along the wheel-spindle c. The outline of the preset is indicated by a broken line in "1st picture". This rim can be arbitrarily designed as long as it is included in the area of the hair & iq. Thus, a large number of 10 can be used to obtain lenses that are suitable for use with different eyeglass frames. In general, the edges of the lens can be easily cut neatly in order to make the mirror 10 200825499 piece/shaped, and to allow the lens to be mounted in the frame and due to aesthetic considerations. Holes 14 can be drilled into the mirror, for example, to accommodate the mounting of screws that are secured to the frame. The general shape of the blank 10 can be designed in accordance with industry standards. For example, as shown in "Fig. 1" and "Fig. 3", it has a circular edge B having a diameter of 60 mm and a side. The convex surface 12 and a rear concave surface 13 are provided. Conventional cutting, trimming and drilling tools can be used to machine the blank 1 to obtain the ophthalmic lens n. In Fig. 1 and Fig. 2, a part of the surface removed area shows the elementary structure of the Maoqu 10 and the ophthalmic lens 11. This structure consists of a network of units (4), 5 (or micro to mircotanks), in which unit 15 is formed in one of the blanks 〇 (as shown in Figure 3). In these figures, the dimensions of the cladding cladding layer i7, unit 15 (or government room) are enlarged to facilitate viewing of the drawings. According to the first embodiment of the present invention, the surface of the blank 10 is divided into a plurality of regions, and in this embodiment, is divided into four regions, namely, a peripheral region Z1, a transition region Z2, a Z3, and a central region Z4. . And measured along the surface parallel to the hair, the size D of the unit 15 is obtained, and the size of the resulting unit 15 also varies in different regions. In the peripheral region Z1, the unit 15 may have a dimension D of less than 2 〇 microns. For example. These dimensions are between approximately 5 and 10 microns. Therefore, when the contour line c is located in the peripheral area Ζ1, such a unit size is such that when the hair chain is cut, the material of the nine-characteristics contained in the single it 15 can be lost. . The incoming characteristics of the blank 10 are only changed by cutting a f in the contour c, especially a peripheral band having a σ of less than about 30 microns. With such a narrow cutting peripheral band, it is further seen that the early 兀15 in the peripheral region Ζ1 is invisible. However, the t area ^4 area '4' early 疋15 feet (four) is more suitable for more than 5 mm, so 'attack some 7 〇 early to produce invisible diffraction or scattering effect, so it does not create visual obstacles to the wearer is not right - The ophthalmic lens causes an aesthetically plausible impact. For example, in the central region Ζ4, the dimension D of the κ κ 兀 兀 15 is approximately between 8 mm and 1 〇. In the transition regions Z2 and Z3, the dimension D of κ > η 1 , /, early 70 15 is more suitable between the outer g region and the dimension D of the single 70 70 70 155 in the central region Z4. For example, the dimension D of j 兀 15 is about 50 ns in the transition zone Z2 and about 1 〇〇 micrometer in the transition zone super Z3. The middle single 15 is separated by a wall 18, and the partition 18 seals the unit. For example, 'the thickness of the partition 18 is approximately 0.1 to 5 microns along the surface parallel to the 1G of the hair. (4) perpendicular to the surface of the hair (4), the height may be between 1 and 1G0 micron, and the better case is between the job and the job. The unit 15 may be square (as shown in Figure 4) or The hexagonal lattice (as shown in "Fig. 5") is arranged in the form of 'and, for example, the thickness d of the partition 18 is 2 years old. Therefore, the size 0 of the unit 15 is equal to the side edge U of the square or hexagon, and the grid of the six-dimensional honeycomb type is best implemented because it can make the group 12 200825499 single 兀 have the best surface. _, the shape of the lattice of the Financing 5 is not limited to the square or six (four), and the shape of the possible types of the financial compatibility with the crystal job is implementable. For example, the lattice shape of the unit 15 is a rectangle, a triangle or an octagon, and a plurality of different types of lattices are arranged in accordance with the size d of the unit 15 of the mosquito. That is, the lattice shape in any of the hairs (4) may be different from the lattice shape in the other. The transparent substrate i6 can be made of glass or different plastics conventionally used in ophthalmic optics. Among them, it can be made into (4) plastic materials, but not limited to polycarbonate, polymethane, polymethylene, polyglycol, poly(p-phenylene bromide) Polymeric fine copolymers of polynorbornene, diethylene glycol bis(propylene carbonate), (mercapto)acrylic acid polymers and copolymers, especially comprising (fluorenyl) acrylic acid polymerized from bismuth And copolymers, sulfur-containing (fluorenyl) di-acids == and copolymers, amino-decanoic acid and thiazide ethylene(tetra) complexes and copolymers, m-oxygens and copolymers, and episulfides Polymers and copolymers. The cladding layer 17 comprising the entire set of units 15 is preferably formed on its front side convex surface 12, and the rear side is said to be secured, and the money is shaped by subtracting I and polishing as needed. Additionally, a graded coating 17 may also be formed over the concave surface of the lens. Obviously, the slope coating 17 can also be formed in a planar optical element. Eighth, as in "Fig. 3", in accordance with the standard practice in ophthalmic optics, an additional layer 19, 20 is formed over the slope layer 17 of the entire set of cells 15. These additional layers have specific functions such as impact resistance, scratch resistance, 13 200825499 colorability, anti-reflective properties, anti-fouling properties, and the like. In the present embodiment, the cladding is formed over the transparent substrate 16, but it is understood that one or more intermediate layers may be formed on the cladding layer and the transparent substrate. Further, it is possible to laminate the hard array elements on the buildup layer on the substrate 16. Thus, for example, ton 5, the buildup layer comprises one of the unit layers containing a substance that provides photochromism to the optical unit, and the other unit layer is for the optical single domain to provide a refractive index change. The additional layer described above may also be formed therebetween. According to the second embodiment of the present invention as shown in Fig. 6, the surface of the hair & is divided into two regions, which are the peripheral region ζι, which contains the smaller size of the military element b 'and another - The central zone Z4' contains a single-unit, the size of which corresponds to the size of the central zone Z4.丨—:/7 图” and “8 图” are not intended to form the unit 16 on the substrate 16 in the “fifth diagram”. The technique used here is similar to that used in electrophoretic displays. For example, these technologies are disclosed in the world patents _ meager, world patent _1281, U.S. patents, U.S. patent 6,327,072, and U.S. Patent 6,579,34Q. In the present invention, the single 5 can also be obtained through the microelectronics method known to those skilled in the related art. For example, the manufacturing process of the unit is, for example, hot and light (hard, soft, negative, and positive). And micro-deposition (for example, by: ς, brush screen printing, ink jet printing, etc.), and the invention is not limited to the above method. 14 200825499 In the example, a beer is taken as a person Under the condition of ultraviolet radiation, before the valley under the condition of the woman, the mask receives the material _, the shirt == the film is covered by a square or hexagonal lattice to conceal the mesh arrangement.

The photoresist is removed in the area of the light-d-d-d to retain a position along the barrier wall. Arrange the ring k over this mask 'the side layer is more anisotropic. = The process continues, the animal ξ 丨 丨 俨 俨 俨 兀 兀 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 衂 衂 衂 衂 衂 衂 衂The state shown in "Fig. 7" begins, and the unit 15 is filled with a photonicity (4) in the form of -^. Money, can be arbitrarily to the hair; 〇 〇; = line pre-treatment, in order to promote the surface of the material of the partition wall 8 and the unit ^.

In addition, it is also possible to use a material print head to inject the substance locally and independently into each unit i5 _. When it is desired that the different units == the master is not miscellaneous (four), the person looking for the job, the surface of the plurality of P brushes is moved and the continuous group unit 15 is continuously filled. In the case where the unit 15 is formed through the selective side, another possible square = first formed - single implant, and then selectively filled with the first substance and closed this t early ^ 'the surface of the element in the process The rest is covered by a mask. Then, by covering at least the cell area except the partition wall area in the anti-money agent mask, and repeating this; the money is engraved, and the new unit is filled with a different substance and covers the new unit. Arbitrarily repeating to distribute different substances along the surface of the component. In order to seal the filled set of monophan 5, a further retaining element 22 is used, for example a plastic film that can be bonded, heat sealed or heat laminated to the top of the partition 18 and the partition. It is also possible to deposit on the area to be sealed, a material which can be polymerized during the melting process, which material does not interact with the material having optical properties contained in the unit 15, and can be made by, for example, heating or irradiation. polymerization. ^ - After the positive unit 15 is filled and sealed (as shown in the "Figure §"), the additional layer 19 of the hoe is completed to complete its production. This type of optic is continuously processed and will be stored for future removal and cut separately according to the user's needs. 16 200825499 If it is not intended to allow the optical properties to be placed after the start of the door: keep the liquid sad or gel state, the substance can be cured in this way. The field and the cymbal of the optical lens K which are continuously arranged by heating and irradiation, for example, are arranged between the two transparent members to hold the material, respectively, are holding members 2, Μ. The holding member 2 is parallel to the surface of the blank 10, and in the field 21, the units 15 are separated by a partition wall and the partition 18 is connected between the two members. In the central area, there are at least 15 divisions at least 15 divisions between the two holding tillers 21 and 22. In the present embodiment, the holding members 21 and 22 are ugly for a plurality of units 15, however, this is not essential to the present invention. The partition 28 is separate from the partition wall 18 and is adapted to be separated from the partition wall 18 by a certain distance. The separator 28 may have a thickness of less than 5 microns along a surface parallel to the optical element. According to this formula, she does not substantially affect the optical properties of Maotan 1Q in the optical properties contained in unit 15. In addition, the partition (4) is perpendicular to the surface of the hair & 10, and has a height ranging from 丨 micron to (10) micro-paste, and its height is more suitable between 丨 micron and 1G micron. It is advantageous to make the height of the partition 28 equal to the height of the partition wall 18. Among them, the partition 28 and the partition 18 can be arbitrarily made of an absorbent material. On the date of this issue, the suction (four) material axis - the species can be at least - part of the visible spectrum of the material 'that is, in the wavelength range of 400 nm to 7 〇〇 nanometer, the absorption material 17 200825499 can at least Absorbs its towel-wavelength light. On the day of the present invention, it is preferable to absorb (4) the material which uses the absorption band as the entire visible spectrum. Whereas the rib is manufactured with 18 materials, the material absorption spacer 28 and the partition wall 18 having the absorption band of the near-infrared band (light wavelength 7 (8) and the ultraviolet wavelength band (light wavelength less than 400 nm) may be selected to have different parts of the same material. Alternatively, the partitions 28 may be arranged in the unit 15 of the central zone Z4, with the addition of the removed elements. Next, as shown in Fig. 9, in a variant embodiment, the entire group of elements j has a hair chain 1G The film 27 is formed in a flexible transparent form. The film 27 can be formed by a similar technique as described above. In this case, the film 27 can be formed on a flat support. The film 27 has a sufficient thickness. Fresh element %, and the unit 25 is filled with optical fine rotation. The towel 25, the unit 25 is provided between the bottom _ 27 simple element 21 and the eight: 1 ^ scale 22. The bottom holding element 21 and the top holding element 22 are used The walls 18 of the single cymbal 15 are connected and arranged to be connected to the largest unit. The t, the partition 18 and the partition (4) are in the film 27 。 body.... The outline _27 can be in a relatively large entanglement Work on the process, and take the membrane step The series can be manufactured in a cost-effective manner, and then the thin layer is transferred to the base of the hair (four), and the shirt is transmitted through the vacuum. In the same case, the film 27 can receive the same as described above. σ, main cover 'or transferred to (d) of the coating _ or a plurality of additional layers 18 200825499 of the substrate 16 In the field of application of the invention, the substance introduced into the unit i5 is related to the substance The refractive index of the substance is modulated along the surface of the hair (4) to obtain a bridged lens. In the first embodiment of the invention, the modulation is transparent to the process of forming the side unit 15. In the case where a substance having a different refractive index is introduced, the substance contained in the unit 15 can be mixed by a liquid which is not mixed, and the ratio of the combination in each of the early 15 is different. In detail, if the unit = medium If the inclusion of the object f is such that the light of the Wei Jing can be along its meridian, then the obtained spectacle lens is a progressive lens. If the light energy and astigmatism in the surface of the Maotan 10 are obtained, a desired distribution is obtained. Second, in a conventional way, it is inferred from this The refraction of the substance enclosed in the unit 15 = cloth is possible. In order to accurately obtain the desired light energy and reddish distribution, it is advantageous to vary the size of the unit 15 depending on the change in the refractive index of the /, 疋. In other words, there must be a large gradient of refractive index change in ^ 10, parallel to the 彳 彳 of the substrate 16; and where the hair (4) rang a small refracting ~ gradient, the vehicle element 15 can have a larger size. In detail, the accuracy of correcting the refractive error can be obtained at the surface - sub- 7; in another embodiment of the present month, the above-mentioned modulation is realized, and the refractive index can be transmitted through the single-weight object The adjustment is performed by irradiation, and the optical function for sputum is obtained by exposing the hair (1) Q or the ophthalmic lens u, and the energy of the film can be changed along the surface shape of the optical element to obtain a desired refractive index, and then the wall is positive. The patient's vision. This light is usually produced by a laser that is similar to a writer unit that is used to support burning of optical discs or other optical memory. The amount of exposure of the photosensitive material can be determined by adjusting the power of the laser and selecting the exposure time. The materials that can be used in this application field are mesoporous materials, liquid crystals, and disc forming components. The liquid crystal body can be fixed by a polymerization-polymerization reaction, for example, by radiation. Therefore, the liquid crystal body can be selectively fixed in such a manner as to introduce a predetermined optical delay into the light wave passing through the liquid crystal body. In the case of mesoporous materials, the refractive index of the material can be controlled by varying its porosity. Further, another useful substance is a photopolymer. One of the well-known properties of the photopolymer is that it can change the refractive index during the light-induced polymerization reaction by irradiation. This change in refractive index is caused by changes in material density and chemical structure. It is recommended to use a photopolymer which has only a very small volume change during the polymerization. In another field of application of the invention, the substance introduced into the unitary oxime in a liquid or gel form is polarized. Among the substances used in this field of application, it is possible to have - a photochromic compound having a central structure, such as spirooxazine, spiro ring (dihydro'-[2,3Ί stupid and oxazine), benzo- The homogenous phase is more than just burnt, alcoholic, and spiro ring (Η) and is more than norm, naphthol [2,1 7]. In detail. The content is disclosed in the following patent application and patent documents: French Patent No. 2763〇7〇, European Special '......... by Ben, European Patent No. 0489655, European Patent No. Q653428, District Rule 'State Patent_ Case No. 7237, French Patent No. 2718447, U.S. Patent No. 6,281,366 20 200825499 or European Patent No. 1,204,714. The material having optical properties may also be a pigment or a pigment suitable for changing the light transmission rate. In the case of having light absorbing characteristics, it is advantageous to change the absorption of light parallel to the surface of the lens and to determine the light absorptivity depending on the polarity of the light. In order to manufacture an optical lens having polarizing characteristics, a liquid crystal in which a dye is mixed may be contained in a unit of the optical element. In other types of ophthalmic lenses to which the present invention may be applied, the ophthalmic lenses described above may be manufactured by an active tether. The change in optical characteristics of the turban may be produced by electrical stimulation. That is, the case of using an electrochromic lens (Electrochromic Lenes) or a variable refractive index lens (for example, see US Patent No. 5,359,444 or World Patent No. 3/〇77〇12). These techniques typically require the use of liquid crystal or electrochemical systems.
